Struct Message 

#[non_exhaustive]
pub struct Message {
    pub role: Role,
    pub parts: Vec<Part>,
}

One message of the conversation history.

The system prompt is not a message: the Agent of agentai sends its own with every request.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

role: Role

Who wrote the message.

parts: Vec<Part>

Content of the message, in order.
